It's been the same thing day after day...low clouds, cool temperatures, and spotty drizzle. The only 'good thing' about a weather pattern such as this is forecasters can use persistence as a good tool to make predictions, at least in the short term. The low pressure system behind all this depressing weather has basically remained in the same position all day long, and will continue to remain stationary for at least another 42 hours. In that amount of time, places like Long Island, NY and coastal Connecticut may receive upwards of 2-4" of rain before the low finally begins to pull away.

So basically expect more of the same weather: low clouds and occasional drizzle/light showers until Friday afternoon/evening. As the low deepens and pulls away to the northeast Saturday night and Sunday, winds will increase out of the northwest 15-30 mph, ushering in cooler air hat has been building for the past few weeks in eastern Canada. Low temperatures Sunday morning may dip into the upper 30s in the Appalachians. Low temperatures closer to DC will likely only fall into the upper 40s/near 50 due to the breezy conditions and airmass modification.

Monday and beyond:
Temperatures Sunday night/Monday morning have the potential to dip further as high pressure moves over head and winds slacken. Areas north and west of the city may see temperatures fall into the lower 40s.

After this, the weather becomes less unsettled, at least for a week or so as high pressure builds and expands over the region. Temperatures will also follow suit with the improved weather conditions--with highs increasing into the mid to upper 70s, with nighttime lows generally around 60.
